NOTES: Read this entire procedure before you begin.
If possible, print the system setup screens (by pressing the <Print Screen>
key) before you turn off the computer, because you will have to restore the
configuration information after the system board is replaced.
1. Disconnect any cables attached to the I/O panel on the back of the com-
puter (see Figure 4-24).
2. Remove the fan shroud as described in "Microprocessor and Heat Sink
Assembly."
3. Remove any installed expansion cards.
Note the location of each connector and the orientation of any cables
attached to the expansion cards before disconnecting these cables.
4. Disconnect all internal cables from the system board.
The cables attached to the PRI IDE, SEC IDE, and FLOPPY connectors (see
Figure 4-18) each have two latches securing them to the system board.
Press the latch on each end of the cable connector, and pull to release the
cable from the system board.
The microprocessor and heat sink assembly (see Figure 4-22), the guide
